5.2.1 Raw
Raw is a pixel format where image data is Bayer RAW untouched by any on board processing. Selecting a Raw format
bypasses the FPGA/color core which disables image processing, such as gamma/LUT and color encoding, but allows
for faster frame rates.
5.2.2 Mono
Mono is a pixel format where image data is monochrome. Color cameras using a mono format enable FPGA/color
core image processing such as access to gamma/LUT.
Y8 and Y16 are also monochrome formats with 8 and 16 bits per pixel respectively.
5.2.3 RGB
RGB is a color-encoding scheme that represents the intensities of red, green, and blue channels in each pixel. Each
color channel uses 8 bits of data. With 3 color channels, a single RGB pixel is 24 bits.
5.2.4 YUV
YUV is a color-encoding scheme that assigns both brightness (Y) and color (UV) values to each pixel. Each Y, U, and V
value comprises 8 bits of data. Data transmission can be in 24, 16, or 12 bits per pixel. For 16 and 12 bits per pixel
transmissions, the U and V values are shared between pixels to free bandwidth and possibly increase frame rate.
YUV444 is considered a high resolution format which transmits 24 bits per pixel. Each Y, U, and V value has 8 bits.
YUV422 is considered a medium resolution format which transmits 16 bits per pixel. Each Y value has 8 bits, but the U
and V values are shared between 2 pixels. This reduces the bandwidth of an uncompressed video signal by one-third
with little to no visual difference.
YUV411 is considered a low resolution format which transmits 12 bits per pixel. Each Y value has 8 bits, but the U and
V values are shared between 4 pixels. The reduces bandwidth by one half compared to YUV444, but also reduces the
color information being recorded.
YUVcan be either packed or planar. Packed is when the Y, U, and V components are stored in a single array
(macropixel). Planar is when the Y, U, and V components are stored separately and then combined to form the image.
Point Grey cameras use packed YUV.
